41、The purpose of this Standard is to establish generic technical requirements that may be referenced by individual telecommunications cable specifications covering products intended for normal outside plant use. The parameters covered provide material, construction, and performance requirements that a
42、re applicable to aircore, polyolefin insulated and jacketed cables of all pair counts, including a variety of shield and jacket combinations and optional compartmental screening. Because this Standard does not cover all details of individual cable design, it cannot be used as a single document for p
43、rocurement of product. It is intended to be used in conjunction with an individual product specification that provides complete design details for the specific cable type and designates the applicable performance requirements. Such individual cable specifications may be prepared either by the user o
44、r the manufacturer. The specification designated for procurement is at the option of the user. 1.2 SCOPE: This Standard covers mechanical and electrical requirements for aircore, polyolefin insulated, copper conductor telecommunications cable. It provides alternative choices for type of insulation,
45、core assembly, color code, sheath design (shielding materials, single or double jackets, and jacket thickness), and screened or non-screened core. 1.3 OPTIONS AND INFORMATION: These cables are traditional outside plant (OSP) cables having a nominal mutual capacitance at 1 kHz of 52 nF/km (83 nF/mile
46、), with attenuation and crosstalk characterized at discrete frequencies up to 6.3 MHz. For cables characterized above 6.3 MHz, refer to ICEA S-99-688, Broadband Twisted Pair Cable, Aircore, Polyolefin Insulated, Copper Conductors. This Standard is arranged in Sections. Each covers one specific area
47、of cable requirement and may be referenced as complete Sections or as individual paragraphs. ANSI/ICEA S-85-625-2011 2 Sections of this Standard where the user may specify a particular option are listed below: 2.1 Conductor Size 3.2 Insulation Type 4.1.3 Core Layup 4.3 Spare Pairs 4.5.2 Undulated Co

49、.2 Length Markings 10.4 Pressurization 10.5 Optional Requirements To assist the user in selection of options and to avoid possible misunderstandings between the manufacturer and user, it is suggested that a check-off sheet similar to that shown in Informative Annex A be used. 1.4 UNITS AND TOLERANCES: SI units (see NIST-SP 811) are specified throughout this Standard except for conductor size. Approximate US equivalents and Fahrenheit temperatures are provided for information only. The rounding-off method of ASTM E 29 shall be used for determin
